One more cross-country storm is forecast to sweep through the central United States before the end of the year. While the rain will be welcome for most across the region, the potential for locally severe storms will threaten the area.
The storm system will move out of the Rocky Mountains and into the Plains through the end of the week. On the cold side of the storm, strong winds and heavy snow can lead to whiteout conditions across the northern Plains.
Rain will begin to develop over southern Nebraska and Kansas on Friday evening before spreading east into Iowa and northern Missouri through the late night.
Ahead of the storm, southeasterly winds will bring moisture from the Gulf of Mexico north into the central and southern Plains. As the storm storms organizes over the region it will tap into this abundant moisture.
A corridor of heavier rain is expected to develop in this area and spread into northern Texas and western Oklahoma where some rumbles of thunder are possible.
On Saturday, rain is expected to move east, drenching areas from southern Wisconsin to eastern Texas.
In the southern Plains, colder air rushing into the region behind the system will clash with warm, moist air that has been pulled north into the area, producing strong thunderstorms from southern Missouri to the coast.

There is potential for some of these storms to become severe. While the main threat will be torrential downpours, the strongest storms can produce gusty winds and perhaps an isolated tornado.
Storms are expected to gradually dissipate through Saturday night as they track east.
Storms will fire once during the day on Sunday as the storm advances east. The area under fire to end the weekend will include western Tennessee to the central Gulf Coast.
Once again flooding downpours and gusty winds will threaten the region. A few isolated tornadoes cannot be ruled out.
While storms rumble across the Lower Mississippi Valley, periods of heavy rain are expected to drench the Ohio Valley.
The risk for flash flooding will increase in areas that see multiple rounds or prolonged periods of heavy rain.
Widespread rainfall totals of 1-2 inches will be common across the region with an AccuWeather Local StormMax™ of 3 inches this weekend.
After a dry start to the month of December, many residents in the central and southern Plains will welcome the wet weather.
